Disposal of storage devices/media

Some (most?) sites have a policy of "putting beyond use" storage devices/media that need to leave their data centre confines for some reason (e.g. failure-replacement, end-of-life).

There are no special SMF records for java stats per se. I must say, that the amount of CPU indicated in your table, is somewhat surprising, as java simply isnt that 'cheap'. Especially, when considering the elapsed timejava very rarely sits around NOT consuming CPU when it has 'things to do'!

I agree. What should not be hard for HSM to create multiple migration subtasks (each with its own ML2 dataset) and have the master task pass one dataset at a time to each subtask (ie: The subtask does the same work as is currently done for a migrate). As each subtask finishes it asks the master ta
